This full metal wide use rotary style hop-up chamber is crafted to perfection and is compatible for use in the G&G Armament M4, KRYTAC M4, and many other M4 series airsoft AEG rifles that accept rotary style hop up units. This hop-up chamber upgrade is constructed fully from die-cast metal with high rigidity to hold up against even the most powerful of gearboxes operating on heavy BBs. The rotary style adjustment knob makes it fast and easy for players to account for various wind conditions and target range, for the most accurate shot every time. The barrel clip attaching the hop-up chamber to the inner barrel is rigid and specially shaped to minimize rotation or movement of the barrel. The Prometheus C-clip design provides an extra level of retention to keep everything locked into place. Replace your rotary style hop-up chamber with this new and improved option from Prometheus.
